Abstract: In order to measure invaded angle of the missile to attack the target, it is presented to use two High-speed camera, near distance gazed fixedly intersection measuring locations for characteristic points of missile middle axes, combining to plane equation is founded by precise measuring characteristic points of target attacked planes before test, invaded angle is calculated. The measuring accuracy could be acquired less than 1°in invaded angle by simulating result proving in these methods, if measure angle precision is less than 13.4″ in High-speed camera. The method is carried out easily in technique, gives a reference to measure invaded angle for missile test attacking land targets.

Key words: Missile test, Attitude measurement, Invaded angle measurement, Intersection measurement
